MILKING-MAGHINE.

lie it known that l, REUBEN l). Ro'ln, a

citizen of the United States, and a resident of Gettysburg, 1n the county ot Adams andl State of Pennsylvania, have invented certain new and useful` Improvements in Milking-Machines, of which the following is a spec-iti lation, reference being had to the accompanying drawings.

rl'his invention has relation to certain new and usetul improvements in manually operated milking machines arranged to be strapped to a cow; and the primary object. otl my invention is toflprovide a readily operated device of this general character, of a lsimple and inexpensive nature and of a compact and durable construction, which shall be capable ot' accurate and convenient adjustment in'position to receive the teats ot a cow in a manner permitting the cow being readily, speedily and effectively milked.

Another object is to provide a milking machine with universally adjusted milking cups.

A further object is to provide a milking machine with an adjustably held cruciform follow plate, arranged to press against the .udder of the cow during the milking operation, to prevent the anima-l from wia-holding her milk. And finally, 'I aim to providev a milking machine in which the operation of the mechanical iustrumentalities simulates the action of a human hand during the act of milking.

With these and other objects in View the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described-and finally pointed out in the appended claims, it being further understood that changesin the speciticstructure shown and described may be made withinthe scope of the claims, without departing from'the spirit of the invention.

In the accompanying drawings forming a part of this specification and in which like numerals of reference indicate similar parts 'in the several views, Figure 1, shows a milking machine constructed according to my invention secured to a cow. Fig. 2, is a top view of themilking machine. Fig. l3, a section on line 3, 3, of Fig. 2. Fig. 4, 1sv a section on line 4, 4, of Fig. 2. Fig. 5, shows a detached detailo fon'e Aof theA rocking blades.

Application led November 21, 1911. Serial No. 661,594.

Manually milking a cow -is a time-consum-v ing and laborious task and in my present invention l provide a mechanical milker,which while speedy. in action, is so simple and can beso easily operated that even children can use the same as effective as adults.

In carrying out the object of my invention, l employ anvoblong carrying plate 1, which near each end are the parallel running slots 2, 2, shown in ,Fig 2, and intermediate ,of its ends this plate gives support to Secured to each end o't` the plate by means of the screws 4, shown in Fig. 3, are the straps 5, each carrying a. hook (i. Rerolubly held within the bearings 3 is the crank shatt. 7, which at one end has the crank 3S, and at thc opposite end the crank 3), astub shaft.V section extending Jfrom the crankC-BS), as shown in Fig. 2, to

which is secured the operating wheel S, having a handle S). Adjustably held within the opening 8 in the carryingplate 1,. shown in Fig. 3, is 'the threaded stem 9, which at its.

upper end carries the cruciform follow plate 1.0. This follow plate 10 is arranged to hold the ndder of 'the cow in adjustable relation to the teat cups and performs a very important function, in that it is found that in the use of. this crucii'orm follow plate the cow is prevented from with-holding her milk. Slidably held within the four slots 2, are the 'set screws 12, clearly shown in Fig. 2, and

these set screws adjustably hold the slotted ears 13. -As shown, the ears may be. readily. adjusted lengthwise or laterally of the plate while being pivotally held upon the screws.

As dis-closed in Fig. 2, each slotted ear 13 carries a teat cup, these cups being slightly oval in cross-section, the cups being secured by means of the seti screws 14, so that the rups may be raised and lowered relative to the carrying plate 1. A practically universaladjustment in a plane co-incident with that of the carrying blade 1, is permitted by means of the screws12 lworking within the slots 2 and the slots of the ears, as shown .in Fig. 2. v.Flach teat cup 2O includes a tubular member open at one end, as shown in Fig. 4, while the opposite or'lower end is contracted and ends in a nipple 21. Near' the lower end4 at one 4point each cup has a threaded boss 22, through which a swivel screw 23 passes to the swivel end 24 of which is movforming a pad, made of felt, rubber or other suitable material. About half of the interior surface of each cup 20, as shown at 2S in Fig.- 4, at a point opposite the threaded boss 22, is transversely corrugated. These corrugations serve in holding the'teats with? in the cups. The upper end of each cup is scalloped to conveniently receive the base of the teat, While above the corrugations are positioned the pads 29. Each blade 26 upon its rear face has `an ear 30 carrying a pin 31, and each pin gives pivotal support to a pitman 32 threaded at its end and carrying a set nut 33, clearly shown in Fig. 4. Intermediate of its ends each pitman has a piston 34. Each piston Works within a tubular crank boxing 35 having an aperturcd end 3G through which a crank stem passes, and held between each boxing end 36 and piston 34 is a coil spring 37, so that each piston is yieldingly, resiliently and adjustably connected to its crank boxing. Each crank boxing 31? has a bearing eye 38, shown in detail in Fig. G, arranged to receive a crank section.I The pitman 32 passes through suitable slots 19 within the cups, as disclosed in Fig. 4. Secured to the lower -end of each cup 20 is a tube 18 the four tubes being secured to a union l as shown in Fig. 3.

The machine is held in operative position by means of a belt 40 having the terminal loops 41,'arranged to engage the hooks (S, in the manner shown in Fig. l. The cups are adjusted to meet the physical peculiarities of thecow and are set by means of the screws 12 and 14. The rocking blades 26 are adjusted by means .of the nuts 33 and the swivel screws 23.

In securing the machine to the cow, the belt 40 is placed on the back of the animal and secured to the hooks 6. A suitable receptacle 16, as shown in Fig. l, is then placed belowvthe union 17 which forms the nozzle to receive the milk. The follower 10 is then given the necessary adjustment so that the same Will press against the udder bet-Ween the teats.v The crank shaft 7 is then slowly rotated enabling the teats to find proper ad justment Within thev cups. When it is certain that the teats are all in proper position, the speed of the shaft 7 is slowly increased. In the operation of the machine all four teats are simultaneously milked.

A milking machine constructed according to my invention is inexpensive and simple in its operation and doesnot clog the teats in the cup. The operation of the blades turther simulates the action of a human hand in the act of milking a cow. The action and pressure of the rocking blades further can be accurately and (amveniently regulated to meet the individual requirements of each animal.

In providing the crucitorm follow plate,

the cow is prevented from with-holding herA milk, which is very important as with mechanical milking machines as ordinarily constructed, it is found that many cows are able to with-hold their milk.

The entire machine being made of metal can be easily sterilized and so contorni to the requirements of sanitation. 'lhe machines are preferably built in several sizes. and finally, after the machine has been adjusted the cow can be milked with ease. accuracy and despatch. l

HavingT thus described my said invention, what I claim as new and desire. to secure by United States Letters Iatent ist-.-

1. A milking machine comprising a plate, cups mounted thereon, movable blades located in the cups, means for operating the blades, and a cruciform plate supported from the first mentioned plate and having `its branches disposed above and between the ou s.

2). A milking machine comprising a plate, cups mounted thereon, movable blades located in the cups, means for operating the blades, a cruciform plate supported from the first mentioned plate and having its branches disposed above and between the cups and means for moving said plates with relation to each other.

3. A milking machine comprising a plate, cups mounted thereon, movable blades located inr the cups, a shaft journaled upon the plate, and resilient means operatively connecting the cups With the shaft.

In testimony whereof atlix my sign aturc, in presence of two witnesses.
